Stefan Berger 52834904d2 nwfilter: re-order lock grabbed by IP addr. learn thread
The IP address learning thread was causing a deadlock when it instantiated a filter while a filter update/change was ongoing. The reason for this was the ordering of locks due to the following calls

virNWFilterUnlockFilterUpdates()
virNWFilterPoolObjFindByName()

The below patch now puts the order of the locks in the above shown order when instantiating the filter from the IP address learning thread.
